Helping to End Addiction Long-term® Initiative (NIH HEAL Initiative®)

What is the NIH HEAL Initiative?

The Helping to End Addiction Long-term® Initiative, or NIH HEAL Initiative®, is an ambitious, high-priority effort across the National Institutes of Health (NIH) to speed scientific solutions to stem the opioid public health crisis and better manage chronic pain conditions. NIMH plays a major role in the initiative by leading research examining how to treat people affected by both opioid use disorder and mental illnesses.

Launched in 2018, the NIH HEAL Initiative includes more than 30 research programs led by most NIH institutes, centers, and offices and in collaboration with the NIH Pain Consortium  and partnerships with community members.

The cross-cutting initiative funds projects nationwide reflecting 26 research priorities  that address urgent, unmet needs across the lifespan and areas of promising scientific opportunity. The ultimate aim of these projects is to find rapid and durable solutions to end the opioid crisis.

More information on the NIH HEAL Initiative and its research programs is available at .

Why is the NIH HEAL Initiative a priority for NIMH?

Many people with an opioid use disorder also experience a co-occurring mental disorder, and over a quarter of these are serious mental illnesses resulting in functional impairment that substantially interferes with major life activities. However, in 2020, more than half of adults with both opioid use and mental disorders had received no mental health services in the past year.

The widespread use of opioids to treat acute and chronic pain has worsened the crisis. People with a diagnosed mental disorder are more likely to be prescribed opioids and have a greater risk of opioid addiction and overdose. Thus, mental illness can make people more vulnerable to opioid use disorder and vice versa. Similarly, people with an opioid use disorder have higher rates of suicide, and the risk is greatest among those who also have a mental disorder.

NIMH prioritizes research that helps people experiencing both mental health and substance use disorders. Through the NIH HEAL Initiative, NIMH is finding ways to provide better care to people experiencing opioid use disorders and mental disorders and reduce suicide risk.

The NIH HEAL Initiative supports a range of programs to develop new or improved prevention and treatment strategies for opioid addiction and co-occurring mental disorders. The initiative also supports solutions to mitigate suicide risk and expand suicide prevention efforts for people who misuse opioids, have an opioid use disorder, or experience acute or chronic pain.

What is NIMH’s role?

NIMH leads a research program that seeks to optimize the delivery of services for people with opioid use disorders, mental disorders, and suicide risk. The program supports a range of innovative services and intervention research to develop, optimize, and test approaches to improve the delivery of care for this vulnerable population. 

  • NIMH oversees research to adapt the collaborative care model  to meet the needs of people with opioid use disorder and co-occurring mental disorders. The collaborative care model is a specific, evidence-based service delivery model for treating mental and behavioral health conditions in primary care settings.
  • NIMH supports a program aimed at reducing suicide deaths  by identifying people who are at risk in primary care. Known as the System of Safety (SOS) , the program seeks to standardize suicide risk identification and prevention throughout health care systems. In another project, researchers are developing a clinical decision tool that prompts primary care providers to assess patients for both opioid use disorder and suicide risk and connect them with appropriate resources.
  • NIMH is helping improve how we identify and treat  mental health, substance use, and pain. Researchers are working with third-party payers to optimize a highly effective intervention known as Maintaining Independence and Sobriety through Systems Integration, Outreach, and Networking (MISSION) . By breaking the intervention into evidence-based components and testing different combinations, the goal is to identify the optimal components that are both effective and affordable.

These three projects are just a few examples of NIMH’s research program aimed at providing services to people with opioid use disorder and mental health needs. All the projects involve conducting large clinical trials and using innovative designs in real-world community settings. Program goals include:

  • Developing improved screening tools to identify people with opioid use disorder and co-occurring mental disorders
  • Creating efficient referral pathways to medication-based treatment for people with opioid use disorder and co-occurring mental disorders
  • Assessing the cost, effectiveness, and sustainability of interventions and services, including in rural and urban areas and areas with a shortage of health care professionals
  • Identifying high-value components of complex interventions   
  • Building new service delivery models for people with opioid use disorder and co-occurring mental disorders
  • Equipping primary care providers to identify and treat people at elevated suicide risk, with a focus on people with opioid use disorder who are at higher risk
  • Developing new tools to help primary care providers identify people at risk for suicide and provide them with critical services

Together, this research program will help expand therapeutic options for treating addiction, including medication-assisted treatment for opioid use disorder and overdose reversal treatments. The research will also improve evidence-based treatments for mental disorders frequently encountered in primary care.
